Default Removing non opening DVD drive

Well this has got me stumped.

I have here a Liteon HDD/DVD recorder (TV programs) that will not eject the
disk that is inside it. There is power, the disc spins, and you can press
eject and it tries to do so but fails.
I can't remove the mech from the unit because the drawer front decal panel
is too big to pull into the unit, and the front part of the chassis prevents
the drive coming out of the front of the unit.
So the drive will not go either backwards or forwards to enable its removal.

If I broke this decal panel off the tray it would, but I don't really want
to do that.

How do you get these things out?

I have done this many a time with CD players, I either eject the drawers and
remove the front panels, or you can usually undo the 4 screws holding the
mech to the chassis, and it will move forward enough to enable the panel to
be removed.
But not this one, its tight against the front chassis.



Cheers,



Gareth.

This one like most computer based DVD units, should have a small pin-hole in the front. Use a paperclip to push the tab on the inside to open it up. The loading belt has probably dried up a bit and doesn't have enough grip to release the clamp from the disk.

Yes, the one I fitted most recently had the same restriction on the front
panel. So there was a bent wire supplied with the drive specifically for
releasing the drawer before fitting. Note the pressure may have to be
quite firm to get the parts moving; it's not spring loaded!

No, this one has no pinhole.

I should have mentioned, this is not the "pop open" type, it is the old
style motor/rubber band/coggy type opening mechanism.

Long shot and you probably tried this, but look for any unidentified holes in the bottom pan of the recorder under the drive. With some luck there may have been a manual opening slot in one of the gears that allow a small screwdriver to open the tray. It's possible the drive mfg provided this, but Liteon may not have added the access hole.

If you have to break off the front trim, it will go back nicely with contact cement or RTV.

No holes that I can see.

I have managed to get the rear end of the metal shield free, the front
screws are not accessible.
I have then also managed to remove the top cover rear screws and I can see
the disk inside if I bend up this cover.
Sounds to me like the mech has jumped some cogs rather than the belt is not
good enough.
I don't think it is going to open whatever I do from this end.

This is the unit.

Looks like I'll have to break the trim off.



Cheers,

Check the bottom plate. There should be an access hole there. All drives that I have seen have some type of access either from the front (pin hole) or the bottom. The bottom hole should expose the side of a gear. Samsung for exmple, has a "tool" that is used to turn the gear. Its really nothing other than another gear on a shaft that fits into the hole on the bottom chassis.

Post a picture of the bottom if you can.

There is a way to remove the top cover. As you removed the screws on the
back already, the cover should be lifted a little and pulled backward. FAIK
there are no screws on the sides but maybe a kind of a click mechanism.

Right, I had to break off the front panel, the decal facia thing is actually
screwed onto the panel from behind.
The mechs plastic top plate underneath the screen cage has 4 screws, the
front were inaccessible without removing the cage, which was secured
underneath the front by 2 inaccessible screws.

So, the only way you can get this mech out is to be able to open the drawer
and remove the front panel first.
You cannot open it by inserting anything through any holes anywhere.

The loading mechanism was jammed because the CD spindle has a pad on it that
appears to be one sided sticky tape?? The CD was strongly glued to it, took
quite a tug to get it off!

Maybe this ring pad had come off somehow, leaving just the self adhesive
bottom bit behind? Dunno.




Thanks for all the suggestions.



Gareth.

Odd. I wonder if that adhesive was originally a non-slip pad that decomposed over time.

Seems to work fine without it.

I've got two LiteOn disk recorders - one an elderly LVW-5045, and a
somewhat later version (similar number, but with something like GL on
the end). With both have had the problems described.

With the older one, with the case cover off so I could see what I was
doing - and with the drive fixing screws removed - I managed to get the
front of the drive pulled forwards. Eventually I was able to detach the
clip-on front of the drive (there's a knack to this) without causing
damage, remove the drive completely, and separate the top and bottom
covers. I then could see exactly where to drill a small hole front panel
to poke in a straightened paper clip to operate the release mechanism.
[Note that, these days, I make sure that I don't leave a DVD in the
drive. However, even without a disk in the drive, it is usually
reluctant to open if it hasn't been opened for a few days.]

With the later version, there is a drop-down flap on the front panel. I
lowered this flap, and with my fingers crossed, I drilled in the panel
behind a hole in the same place as the older recorder. With some
persistence, I was then able eject a disk that had become glued in place
on the 'double-sided sticky rubber' on the central capstan. So far, I
haven't dismantled the machine to see what can be done to make the
sticky rubber un-sticky.

I removed all traces of the sticky rubber, it took some doing with a flat
blade screwdriver and some potent solvents.

I don't know what it is doing there in the first place.



And yes, the mech had the capability to be teased open with a tool, had a
hole been provided in the unit to do so.


Gareth.

Its purpose is probably to absorb the vibration and make the unit somewhat quieter and stop the disk from slipping when speed changes suddently.
